Abstract

A battery system includes a battery pack configured to include at least a plurality of battery cells that are connected in series, a monitor that monitors a state of the plurality of battery cells, and a controller to which an output of the monitor is supplied, a battery pack module in which the battery pack in a first order to the battery pack in an Nth order are connected in series, and an integrated controller that is connected with the battery pack in the first order of the battery pack module. Isolators are respectively disposed among the battery pack in the first order to the battery pack in the Nth order, and a signal is transmitted from the battery pack in an order of n-1 (N≥n≥2) to the battery pack in an order of n via one of the isolators.
